CURTAIN-FIXTURE.

SPECIFICATION forming part of Letters Patent No. 252,851, dated January24, 1882.

Application filed October 11,1881. (No model.)

To all whom it may concern Be it known that I, HENRY S. WING, ofAshtabula, in the county of Ashtabula and State of Ohio, have inventedcertain new and useful Improvements in Curtain-Fixtures; and I do herebydeclare the following to be a full,clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention relates to an improvement in curtain-fixtures, the objectbeing to provide an attachment for curtain-rollers which shall be cheapand simple in its construction and adapted to hold the roller in a fixedposition by friction.

With these ends in view my invention consists in the combination ofparts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective ofmyinvention. Fig. 2 is a longitudinal section taken through a portion ofthe roller and the friction holding device, and Fig. 3 is amodification.

A represents a bracket provided with a flange,a, for its attachment tothe window-casing by screws 1). Bracket A is formed with a circulardisk, B, and a cord eye or loop, b, being made integral with thebracket, or being made separate therefrom and riveted or solderedthereto.

0 represents the curtain-roller, one end thereof having a socket, 0,formed therein, within which is inserted a spiral spring, D, the outerend of the spring bearing against the inner face, d, of the bracket.

E is a friction-disk, which may be made of any sheet metal desired, butis preferably formed of sheet-steel. Disk E may be made of any desiredformas, for instance, it may be square, hexagonal, or star-shaped, asillustrated in the drawings. The points 6 of the friction-disk areslightly curved toward the outer face of the bracket and rest upon theouter edge of the bracket-disk B, whereby the tension of the spring-armsof the disk may be utilized to the best advantage, as will hereinafterappear. F is a shank formed of a rod secured at one end tothefriction-disk and screwthreaded at its opposite end, whereby it maybe attached to the end of the roller.

Having described the construction and form of the several parts of myimprovement, I will now briefly describe its operation.

The holding force of the curtain is regulated by adjusting thefriction-disk E, which latter, on being turned in onedirection, hasitsspringarms drawn against the bracket, thereby utilizing the tension ofthe arms of the disk in holding the rollerin a stationary position andsupporting the curtain in any desired adjustment. 6c The spiral springinserted in the end of the roller tends to force the roller away fromthe bracket, and thus holds the friction-disk in snug engagement withthe supporting-bracket.

' By turning the friction-disk its tension may be regulated to upholdany size or weight of curtain.

Instead of employing a spiral spring within a socket in thecurtain-roller, I may use a rubber block with a washer interposedbetween '70 the end of the roller and the inner face of the bracket.

The friction-disk may be corrugated; or it may be made cup-shaped, andprovided with a serrated edge that bears against the support- 7 5 ing-bracket.

Instead of employing the form of bracket shown in the drawings, it maybe made as shown in Fig. 3, and the same results secured.

Having fully described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-- 1. Inacurtain-fixture,thecombination,-with the roller and the screw-threadedshank,of the bracket through which the shank extends, a sprin D,and diskE,the latter being secured to the end of the shank and adapted to bearagainst the outer side of the bracket, substantially as set forth.

2. In acurtain-fixture,thecon1bination,with the roller having the socketc, of the screwthreaded shank F, disk E, secured thereto, the bracket A,and spring D, surrounding said shank within its socket, said disk Ebeing adapted to have frictional engagement withthe diskB of thebracket, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

HENRY S. WING.
